Le but de la présente invention consiste à éliminer les in- The object of the present invention is to eliminate the
convénients précités et à offrir au surplus divers avantages. Par une intuition géniale, on a réalisé une semelle plantaire capable de contenir une quantité de gaz bien dosée, particulièrement de l'air, et on a subdivisé la chambre destinée à contenir ce gaz en plusieurs sections dont quelques-unes de celles-ci communiquent aforementioned advantages and, in addition, to offer various advantages. By an ingenious intuition, we realized a footbed capable of containing a quantity of well-dosed gas, particularly air, and the chamber intended to contain this gas was subdivided into several sections, some of which communicate with each other.

Selon une variante, des qualifications orthopédiques cor- According to one variant, orthopedic qualifications cor-
rectives peuvent être attribuées au sous-pied pour les cas des genoux valgus et des genoux varus. La variante consiste à rendre gonflables indépendamment les deux chambres à air longitudinales servant à soutenir l'arcade métatarsienne interne et externe. En effet, en gonflant plus fortement la partie correspondant à l'ar- cademétatarsienne interne, oncorrige les genoux valgus, tandis qu'en gonflant plus fortement la partie correspondant à l'arcade rectives can be assigned to the subfoot for cases of valgus knees and varus knees. The variant is to make independently inflatable two longitudinal air chambers used to support the inner and outer metatarsal arch. In fact, by inflating more strongly the part corresponding to the internal aremetometatarsal, the corns valgus are corrected, whereas by inflating more strongly the part corresponding to the arch.

Pour mieux expliquer les caractéristiques de la présente invention, celleci est décrite en détail ci-après en se référant aux dessins qui représentent schématiquement et démonstrativement To better explain the features of the present invention, this is described in detail hereinafter with reference to the drawings which show schematically and demonstratively

Les lignes de soudure 21 et 22 s'attachent à la soudure périphérique 12 et forment donc deux chambres à air 3 et 4, tandis que les lignes de soudure 23 et 24 définissent une seule chambre à air 5, les sections 5', 5" et 5"' de cette chambre étant associées les unes aux autres par des interruptions de soudure 50. Les chambres 3, 4 et 5 sont remplies de gaz selon l'une des méthodes connues, c'est-à-dire au moyen d'une seringue ou à l'aide d'une soupape convenable non substantially consists of two sheets 1 and 2 welded to each other exactly along their periphery 12, as well as along the four transverse lines 21, 22, 23 and 24 and a substantially longitudinal line 11. The weld lines 21 and 22 attach to the peripheral weld 12 and thus form two air chambers 3 and 4, while the weld lines 23 and 24 define a single air chamber 5, the sections 5 ', 5 "and 5" 'of this chamber being associated with each other by welding interruptions 50. The chambers 3, 4 and 5 are filled with gas according to one of the known methods, that is to say by means of of a syringe or with a suitable valve

The specific pressure thus reported to the area of the whole foot is reduced to a minimum. The foot is supported in all parts, including the internal metatarsal arch, in essence without the possibility that, even in the presence of strong pressure exerted on the heel, for example, especially during
